Abstract:

A digital computer program is used to obtain solutions to a two-dimensional nonlinear analysis for large-signal traveling-wave devices and klystrons. Various values of axial magnetic field and space charge are used in the solutions. Theoretical work in the solution of large-signal phenomena in multi-stream microwave devices by a density function method is presented. Some of the results obtained in checking out the computer program are shown. Phase shift data for a velocity tapered tube is compared with that for a conventional tube. Under certain conditions the former is found to be more desirable from a standpoint of phase shift. Extensions and modifications to the digital computer programs for electron guns are described. Relativistic effects and arbitrary axially symmetric magnetic fields can be taken into account. Some of the considerations in employing a Crestratron in a lownoise high-power amplifying chaing are described. Several techniques are presented in keeping the noise figure low in a Crestatron.
